DETAILED DESCRIPTION

Wireless network site survey systems and methods are described herein. For example, one or more embodiments include placing a number of wireless nodes a first set of locations, placing a root access point at a particular location in communication with at least one of the number of wireless nodes, receiving communication metrics from the number of wireless nodes at the first set of locations and the root access point, moving the number of wireless nodes to a second set of locations that is in communication with the root access point at the particular location, receiving communication metrics from the number of wireless nodes at the second set of locations and the root access point, and generating a node coverage map based on the received communication metrics, wherein the node coverage map includes the first and second set of locations.

A wireless network site survey can be used to determine a number of communication metrics (e.g., connection qualities, received signal strength indication (RSSI), link quality indicator (LQI), received signal quality indicator (RSQI), etc.) for a wireless network (e.g., computer network, telecommunication network, local area network (LAN), wide area network (WAN), etc.). The wireless network site survey can be performed prior to installation of the wireless network by placing a plurality of wireless nodes at a number of locations. The wireless nodes can include a free router (e.g., wireless communication device, etc.) configured to send and/or receive a number of beacon messages to a computing device and/or other wireless nodes.

The wireless nodes can be place throughout a particular area to determine a number of communication metrics for wireless network to be installed in the particular area. The wireless nodes can communicate with each other to determine a number of communication metrics between each of the wireless nodes and can communicate with a computing device to determine a number of communication metrics between the computing device and the wireless nodes. The computing device can use the number of communication metrics to generate a wireless node map and/or heat map for the particular area. The wireless node map and/or heat map can be used to determine wireless routing device locations for installing a wireless network.

In the following detailed description, reference is made to the accompanying drawings that form a part hereof. The drawings show by way of illustration how one or more embodiments of the disclosure may be practiced.

These embodiments are described in sufficient detail to enable those of ordinary skill in the art to practice one or more embodiments of this disclosure. It is to be understood that other embodiments may be utilized and that process, electrical, and/or structural changes may be made without departing from the scope of the present disclosure.

As will be appreciated, elements shown in the various embodiments herein can be added, exchanged, combined, and/or eliminated so as to provide a number of additional embodiments of the present disclosure. The proportion and the relative scale of the elements provided in the figures are intended to illustrate the embodiments of the present disclosure, and should not be taken in a limiting sense.

As used herein, “a” or “a number of” something can refer to one or more such things. For example, “a number of wireless nodes” can refer to one or more wireless nodes.

FIG. 1 illustrates an example of a wireless network site survey system 100 in accordance with one or more embodiments of the present disclosure. The wireless network site survey can include a number of wireless nodes (e.g., wireless nodes 102-1, 104-1, 106-1, etc.) placed at a number of locations. The number of wireless nodes can be placed at a number of locations that can enable each of the number of the wireless nodes to be in communication with a number of other wireless nodes. For example, wireless node 104-1 can be placed at a particular location that is close enough to enable wireless node 104-1 to communicate (e.g., send and/or receive beacon messages, etc.) with wireless node 102-1.

The distance and/or position between two wireless nodes can be different depending on a number of factors (e.g., type of wireless node, objects between wireless nodes that can cause interference, etc.). The number of factors can include a number of properties of the wireless nodes (e.g., signal strength, etc.) and/or a number of properties of the area (e.g., wall positions, materials within structure, etc.) being surveyed. For example, two wireless nodes can be placed at a greater distance if the signal strength of the two wireless nodes is greater compared to two wireless nodes with a lower signal strength.

Each of the number of wireless nodes can communicate (e.g., send and/or receive beacon messages, etc.) with a computing device 110. For example, wireless node 108 can communicate with wireless node 102-1 and/or wireless node 106-1. The number of wireless nodes can communicate by sending and receiving a number of beacon messages (e.g., advertisements, message including information relating to the sending wireless node, etc.).

The number of beacon messages can be analyzed by the computing device 110 and/or the receiving wireless node to determine communication metrics between the sending wireless node and the receiving wireless node. For example, a beacon message can be sent from wireless node 106-1 to wireless node 108 via communication path 118-1. The received beacon message can be analyzed by wireless node 108 and/or sent to computing device 110 via communication path 116 to be analyzed by computing device 110.

Beacon messages can be sent and received between the wireless nodes and the computing device 110. For example, beacon messages can be sent from wireless node 102-1 to the computing device 110. The computing device 110 can determine a number of communication metrics of the wireless nodes based on the sending and receiving of beacon messages between the wireless nodes and the computing device 110. For example, the computing device 110 can determine a number of communication metrics between the computing device 110 and wireless node 108 through communication via a wireless connection 116. The communication in this example can include the sending and receiving of beacon messages similar to the sending and receiving of beacon messages between the number of wireless nodes.

The communication between the computing device 110 and the number of wireless nodes can include information about communication metrics between the number of wireless nodes. For example, communication sent from wireless node 108 to the computing device 110 can include a number of communication metrics between wireless node 108 and wireless node 102-1. That is, the communication metrics can be determined by each of the wireless nodes and the determined communication metrics can be sent to the computing device 110.

The communication metrics can include a number of metrics that can indicate a link quality between the sending wireless node and the receiving wireless node. For example, metrics that can indicate a link quality can include: RSSI, LQI, RSQI, among other metrics to evaluate a link quality between the sending wireless node and the receiving wireless node.

The communication metrics between a number of wireless nodes and communication metrics between a number of wireless nodes and the computing device 110 can be used to generate a wireless node coverage map of a first area 112. The wireless node coverage map can include communication metrics for the first area 112. For example, the wireless node coverage map can include potential link quality within the first area 112.

One of the number of wireless nodes can be a root access point (RAP) and/or a master wireless node. The RAP can be a wireless node that can be used to leap frog the remaining wireless nodes to a second area 114. A leap frog can include placing the remaining wireless nodes (e.g., nodes other than the RAP, etc.) to a second location within the area that is desired to be surveyed.

The RAP can be wireless node 108. That is, wireless node 102-1, wireless node 104-1 and wireless node 106-1 can be moved to a second location. The second location for each node can be represented by wireless node 102-2, wireless node 104-2, and wireless node 106-2. The RAP wireless node 108 can remain in the same location. The RAP wireless node 108 can communicate with a number of nodes at the second location. For example, the RAP wireless node 108 can communicate (e.g., send and/or receive beacon messages, etc.) with wireless node 102-2 and/or wireless node 106-2. Similarly, wireless node 104-2 in the second position can communicate with wireless node 106-2 and wireless node 102-2 in the second position.

The wireless nodes at the second location can communicate with the computing device 110 (e.g., portable computing device capable of moving through a particular area, etc.). The communication between the wireless nodes at the second location and the computing device 110 can be similar to the communication between the wireless nodes at the first position and the computing device 110 as described herein. For example, the computing device 110 can communicate with the RAP wireless node 108 via communication path 116. In addition, the computing device 110 can communicate with wireless node 106-2, wireless node 104-2, and/or wireless node 102-2.

The communication between each of the wireless nodes and the computing device 110 can include the sending and/or receiving of a number of beacon messages. The beacon messages can include a number of communication metrics between the computing device 110 and each of the number of wireless nodes. For example, the computing device 110 can communicate by sending and/or receiving a number of beacon messages with wireless node 104-2. The computing device 110 can determine a number of communication metrics based on the number of received and/or sent beacon messages.

The number of beacon messages sent by the number of wireless nodes to the computing device 110 can include communication metrics for a link quality between the number of wireless nodes. For example, a link quality can be determined by RAP wireless node 108 based on communication with wireless node 102-2 and sent through a beacon message to the computing device 110. The computing device can receive the beacon message from the RAP wireless node 108 and utilize the link quality between the RAP wireless node 108 and wireless node 102-2 in surveying the communication metrics for area 114.

The computing device 110 can utilize the received beacon messages from the number of wireless nodes and the received communication metrics between each of the number of wireless nodes to determine a projected communication between the wireless nodes at the first position and the wireless nodes at the second position. For example, the computing device 110 can utilize the communication metrics to determine a projected communication 120-1 between wireless node 102-1 at the first position and wireless node 102-2 at the second position. In this example, wireless node 102-1 can be the same physical node as wireless node 102-2. For example, a physical wireless node 102-1 can be placed at a particular first location for a determination of the communication metrics at the first position and the wireless node 102-1 can be moved (e.g., leap frog over RAP wireless node 108, etc.) and be a physical wireless node 102-2 at a second position for a determination of communication metrics at the second position.

Similarly, wireless node 106-1 can be moved to a second location and be wireless node 106-2. The projected communication 120-2 can be determined by the computing device 110 based on communication metrics of the first location and the second location of the wireless nodes.

By utilizing a plurality of wireless nodes placed at a number of locations within proximity to communicate with each other as described herein, a total area can be surveyed by measuring communication metrics for a number of areas within the total area and combining the number of areas to determine communication metrics for the total area. From the survey of area 112 and area 114 a wireless node coverage map can be generated that includes area 112 and area 114. The wireless node coverage map can be used to determine node locations for installing a wireless network. The wireless node coverage map can be generated by moving the computing device 110 to a number of different locations within area 112 and area 114 and determining communication metrics at each of the number of locations. The leap frog as described herein can be accomplished utilizing the computing device 110 within area 112 when the wireless nodes are placed within area 112 and moving to locations within area 114 when the wireless nodes are leap frogged to locations within area 114.

FIG. 2 illustrates an example method 230 for a wireless network site survey in accordance with one or more embodiments of the present disclosure. The method 230 can be utilized to survey a total area that includes a plurality of areas (e.g., a first area and a second area, etc.). A survey can include determining a number of communication metrics for the total area. For example, the number of communication metrics can include a link quality for a number of positions within the total area. The link quality, as described herein, can include various quality measurements (e.g., connection qualities, RSSI, LQI, RSQI, etc.) for a wireless network (e.g., computer network, telecommunication network, local area network (LAN), wide area network (WAN), etc.) of a wireless network.

At block 232, method 230 includes placing a number of wireless nodes at a first set of locations. The number of wireless nodes can include nodes that are capable of sending and/or receiving wireless messages. For example, the number of wireless nodes can be free routers capable of sending and receiving a number of beacon messages. The number of wireless routers can be placed at the first set of locations that enable the number of wireless routers to each communicate with other wireless routers. For example, a first wireless node can be placed at a first location that can communicate (e.g., send and receive beacon messages, etc.) with a second wireless node placed at a second location.

At block 234, method 230 includes placing a root access point (RAP) at a particular location in communication with at least one of the number of wireless nodes. The RAP can be a wireless node similar to the number of wireless nodes placed at the first set of locations. The RAP can be a stationary wireless node through a number of movements of the number of wireless nodes during the surveying method 230.

At block 236, method 230 includes receiving communication metrics from the number of wireless nodes at the first set of locations and the root access point. Receiving communication metrics can include sending and/or receiving a number of beacon messages between the number of wireless nodes. The sending and/or receiving the number of beacon messages between the number of wireless nodes can be used to determine communication metrics between the number of wireless nodes.

As described herein, the communication metrics that are determined based on the communication between the number of wireless nodes can be used to determine a node coverage map (e.g., representation of link quality for particular locations within the particular area, etc.) for a particular area. For example, communication metrics between each of the number of wireless nodes and communication metrics between the wireless nodes and a computing device can be used to determine a node coverage map for the first location. In another example, a computing device can be moved to an area surrounding each of the number of wireless nodes to determine a number of communication metrics between the computing device and each of the number of nodes. The computing device can utilize the communication metrics to generate a node coverage map that can be represented and displayed on the computing device as a heat map.

At block 238, method 230 includes moving the number of wireless nodes to a second set of locations that is in communication with the root access point at the particular location. Moving the number of wireless nodes to a second set of locations can be done to generate a node coverage map that includes area around the second set of locations. Moving the number of wireless nodes to the second set of locations can include moving the physical wireless nodes to the second set of locations.

At block 240, method 230 includes receiving communication metrics from the number of wireless nodes at the second set of locations and the root access point. Receiving communication metrics from the number of wireless nodes can include determining the communication metrics by analyzing sent and received beacon messages between the number of wireless nodes and between the number of wireless nodes and a computing device.

Each of the number of wireless nodes at the second set of locations can send communication metrics to the computing device. For example, communication metrics can be determined between a first wireless node and a second wireless node. In this example, the determined communication metrics can be sent to the computing device by the first wireless node and/or the second wireless node via a number of beacon messages. In the same example, communication metrics between the computing device and number of nodes can be determined from the sending and receiving of the number of beacon messages. That is, each of the number of wireless nodes can broadcast communication metrics with each of a number of surrounding wireless nodes. In this example, the computing device can receive communication metrics and/or a link quality for each of the wireless nodes when communicating with a single wireless node.

The computing device can be a portable computing device that can be moved to various locations within the first set of location and second set of locations to determine communication metrics between the computing device at the various locations and each of the number of wireless nodes. For example, a user can move the computing device throughout a first area that includes the first set of locations to determine communication metrics for each of the number of wireless nodes at various locations. In this example, the computing device can receive communication metrics for communication between the computing device and each of the number of wireless nodes as well as communication metrics for communication between each of the number of wireless nodes.

The number of beacon messages can be sent periodically over a fixed channel. For example, the number of beacon messages can be sent by the number of wireless nodes over a predetermined wireless channel. The predetermined wireless channel can include a particular wireless signal. The particular wireless signal can be wireless signal that can be used when installing an operating wireless network.

At block 242, method 230 includes generating a node coverage map based on the received communication metrics, wherein the node coverage map includes the first and second set of locations. The received communication metrics from the number of wireless nodes can be used to generate the node coverage map. The node coverage map can include a heat map that can represent communication metrics for an area that includes the first location and the second location. The heat map can be a graphical representation of the various communication metrics for an area surrounding the first location and the second location.

The node coverage map can be used to determine a number of physical locations within the area for a number of wireless routing devices for the installation of a wireless network for the area. For example, the node coverage map can be used to determine locations for the number of wireless routing devices based on the communication metrics between the number of wireless nodes and between the computing device and each of the number of wireless nodes. In this example, the node coverage map can be displayed and it can be used to determine that optimal communication metrics that can be achieved for the installation of the wireless network by placing the wireless routers at a number of specific locations.

The communication interface can be integrated in the computing device 350 and/or be an external card.

The computing device 350, as described herein, can also include a computer readable medium (CRM) 352 in communication with processing resources 350-1, 350-2, . . . , 350-N. CRM 352 can be in communication with a device 358 (e.g., a Java® application server, among others) having processor resources 350-1, 350-2, . . . , 350-N. The device 358 can be in communication with a tangible non-transitory CRM 352 storing a set of computer-readable instructions (CRI) 354 (e.g., modules) executable by one or more of the processor resources 350-1, 350-2, . . . , 350-N, as described herein. The CRI 354 can also be stored in remote memory managed by a server and represent an installation package that can be downloaded, installed, and executed. The device 358 can include memory resources 352, and the processor resources 350-1, 350-2, . . . , 350-N can be coupled to the memory resources 352.

For example, the processor resources 350-1, 350-2, . . . , 350-N can execute CRI 354 to perform a number of functions (e.g., generating a node coverage map based on the received communication metrics, etc.). A non-transitory CRM (e.g., CRM 352), as used herein, can include volatile and/or non-volatile memory. Volatile memory can include memory that depends upon power to store information, such as various types of dynamic random access memory (DRAM), among others.

The non-transitory CRM 352 can be integral, or communicatively coupled, to a computing device, in a wired and/or a wireless manner. For example, the non-transitory CRM 352 can be an internal memory, a portable memory, a portable disk, or a memory associated with another computing resource (e.g., enabling CRIs to be transferred and/or executed across a network such as the Internet).

The CRM 352 can be in communication with the processor resources 350-1, 350-2, . . . , 350-N via a communication path 356. The communication path 356 can be local or remote to a machine (e.g., a computer) associated with the processor resources 350-1, 350-2, . . . , 350-N. Examples of a local communication path 356 can include an electronic bus internal to a machine (e.g., a computer) where the CRM 352 is one of volatile, non-volatile, fixed, and/or removable storage medium in communication with the processor resources 350-1, 350-2, . . . , 350-N via the electronic bus. Examples of such electronic buses can include Industry Standard Architecture (ISA), Peripheral Component Interconnect (PCI), Advanced Technology Attachment (ATA), Small Computer System Interface (SCSI), Universal Serial Bus (USB), among other types of electronic buses and variants thereof.

The communication path 356 can be such that the CRM 352 is remote from the processor resources e.g., 350-1, 350-2, . . . , 350-N, such as in a network relationship between the CRM 352 and the processor resources (e.g., 350-1, 350-2, . . . , 350-N). That is, the communication path 356 can be a network relationship. Examples of such a network relationship can include a local area network (LAN), wide area network (WAN), personal area network (PAN), and the Internet, among others. In such examples, the CRM 352 can be associated with a first computing device and the processor resources 350-1, 350-2, . . . , 350-N can be associated with a second computing device (e.g., a Java® server).
